Microtensile Bond Strength of a Novel Adhesive System Containing 0.2% Chlorhexidine
Abstract
Objective: This in-vitro study looks at the immediate and 16 week micro tensile bond strength (MTBS) of Peak Universal Bond (PUB), a novel adhesive system containing 0.2 % chlorhexidine (CHX), in a self etch (SE) application. Materials and Methods: Thirty six non-carious extracted third molars were randomly assigned to one of three test group based on dentinal adhesive system. Group A: Clearfil SE, Group B: Clearfil SE +0.2 % CHX, Group C: PUB. All teeth were sectioned parallel to cemento-enamel junction (CEJ) mid-coronally. Dentin adhesive was applied to exposed dentinal surfaces per manufacturers instructions before adding composite resin (Filtek Z250, Shade A2). Samples were tested for immediate (24 hour) and for 16 week MTBS. Proc GLM of SAS protocol, Tukey tests, and studentized T-test were used for statistical analysis. Results: Group A-0 displayed significantly less immediate MTBS than B-0 and C-0. At 16 weeks Group A-16 displayed a significant decrease in bond strength with a loss of 10.6 MPa. Groups B and C showed no significant decrease in bond strength at 16 weeks. Conclusion: The addition of 0.2% CHX into Clearfil SE and PUB self etching primers acts to prolong dentin bond strength over a 16 week time period without significantly inhibiting immediate bond strength.
